    coreboot: add imd library
    
    The imd (internal memory database) library provides a way to
    track memory regions by assigning ids to each region. The implementation
    is a direct descendant of dynamic cbmem. The intent is to replace
    the existing mechanisms which do similar things: dynamic cbmem, stage
    cache, etc.
    
    Differences between dynamic cbmem and imd:
    - All structures/objects are relative to one another. There
      are no absolute pointers serialized to memory.
    - Allow limiting the size of the idm. i.e. provide a maximum
      memory usage.
    - Allow setting the size of the root structure which allows
      control of the number of allocations to track.
